Sasol Ottery are ******* stay away

I just had the worst service from Sasol Ottery. I wanted to put R150 in the tank of car. I asked if they can scan to pay and the petrol attendant said yes but we first check if it goes through. So I scan the QR code and the money is deducted from my card. They then proceed to tell me they can't put the petrol in because no receipt printed on the card machine. I then went inside to try and resolve the issue showing the manager or cashier my proof on my phone. I was then told my proof means nothing because phones can be edited. I then demanded to speak to the owner. They then called him and gave the phone to me. The owner very arrogant tells me that if no receipt printed then the money never went into his account. Then he proceeds to tell me i will not get my money back. So I ask you Sasol is this the kind of ***** that is allowed to continue with your name. How many people has this been done to. The owner flat out refused to hear my side and just said " you not getting any money back" regardless of me having proof of receipt on my phone.
